GUIDE MEANS ro a whereas AND SIMILAR MACHINES.

Application filed May 21, 1823. Serial No. 640,431;

To all whom it may concern: 7 7

Be it known thatI, ALONZO E. RHoAnEs, a citizen of the United States,and resident of Hopedale, county of Worcester, and State ofMassachusetts, have invented an Improvement in Guide Means for Warpersand Similar Machines, of which the fol-' lowing description, inconnection with the accompanying drawing, is a specification, likecharacters on the drawing representing like parts.

This invention relates to a yarn winding machine wherein the yarn isWound upon a core in a cylindrical mass by means of one or more drivenwinding drums mounted in parallelism with the core and acting byperipheral engagement with the yarn mass on the core to effect thewinding operation,

ticularly designed for a balling machine wherein a number of yarns takenfrom spools or bobbins on a creel are gathered together in a chain orrope and wound separately on a yarn receiver in the form of a beam orroll, but in its broader aspects the invention is not limited to theparticular type of yarn winding machine.

The present invention in its broader aspects is subsidiary to theinvention-dis- BU closed in my application filed concurrently herewith,Serial No. 640,429, and in some respects is also subsidiary to theinvention disclosed in my application filed concurrently herewith,Serial No. 640,430.

The object of the invention is primarily to provide guides supportedrigidly from the frame of the machine at right angles to the axis of theyarn receiver which act to guide the yarn receiver in its transversemovement during the winding operation and thus to prevent longitudinalmovement In the case of a of the yarn receiver. balling machine it is ofgreat importance that the yarn receiver shall remain during the entirewinding operation in the same longitudinal position relatively to theframe of the machine, the winding drums, and the limits of traverse ofthe trumpet or other device from which the chain or rope of yarn passesto the yarn receiver. Otherwise there is danger of overlapping of theyarn at the ends of the yarn receiver and the formation of an imperfectball.

With the present invention the yarn receiver beam or roll on which thechain or rope .of yarn is wound is accurately main- .tained in a fixedlongitudinal position so that during'the' winding operation and duringthe relative transverse movement which" takes place between" it and thewinding drum or drums the chain or rope of yarn is placed accurately andthere is no danger of overlapping at the-ends.

These and other objects and features of the invention will appear morefully. from the accompanying description and drawings and will be theclaims. y In the drawings:

particularly pointed out in Fig. 1 is a front elevation of the' 'mainportions of a familiar type of ballingv machine with a preferred form ofthe'present invention embodied therein; The invention in its preferredform is parconstrucof the present invention is ofa similar type to thatshown in my prior Patent No. 867 ,153, granted September 24, 1907, andas the general construction and operation of" such machine is well-knownand'familiar'to those skilled in the art, it is only necessary here todescribe those parts particularly concerned with the present invention;

Such a machine usually comprises a frame 1 having side members 1. Eachside mem ber has extendingupwardly therefrom the upright standards 2provided with elongated open-vertical slots 3 to receive the journals40f the beam, roll or cylinder '5 on which the ball of yarn is wound.Theseopen slots are closed by arms 6 fulcrumed tive position by a lockor'catch 8.

Theball or mass of yarn Q-during the winding operationrests upon a pairof driven winding drums 10' arranged beneath at 7 on the frame and eachheld in operaand in parallelism with the'axis-of the'roll 5 and havingthe journals 11 mounted in bearings in the side members of the frame.

The winding drums, being driven at the same speed and in the samedirection, in the usual manner, serve to wind the yarn upon the roll 5and as the diameter of the yarn mass 9 increases, the journals 4 of theroll 5 move transversely away from the winding drums and ride alongtheslots 3.

The yarns, which are usually taken from spools or bobbins mounted in acreel, are

gathered into a chain or rope and passed through a trumpet 12 which hasa traverse motion in front of and adjacent the beam or roll 5. Thiscauses the chain or rope of yarn to be wound evenly in spirals of theproper pitch in the formation of the ball. The trumpet 12 is usuallymounted on a carriage 18 sliding on a transverse rod 14: mounted in theside member 1 of the frame. At its lower end the carriage 13 is providedwith a follower 15 fitting in the double or cross threads 16 of atraverse shaft 17 journalled in bearings in the side members 1 of theframe and also extending in parallelism with the journals of the windingdrums and the beam or roll.

It is very important that the longitudinal position of the beam orroll 5shall be accurately maintained with respect to the limits of traverse ofthe trumpet 12. Otherwise the yarn may overlap at the ends of the balland thus form an imperfect ball.

This difliculty is obviated in the present invention by providing, inthe preferred form illustrated, apair of guides 18 in the form'of flatplates'supported rigidly from the frame-and extending at right angles tothe axis of the yarn receiver in its-transverse movement during thewinding I operation and thus preventing longitudinal movement thereofrelatively to the frame and to the limits of traverse of the trumpet.These plates 18 preferably co-act with the yarn receiver by abuttingthe-ends of the journals at so that as the beam or roll 5 moves awayfrom or toward the winding drums the ends of its journalsi are guided bythe guide plates 18.

In order to provide the necessary adjustment of'the guides relatively tothe journals 4: these guides are made bodily adjustable longitudinallyof the axis of the beam or roll 5. This adjustment is secured by aplurality of screw threaded supports 19 secured in and projectinglongitudinally from the sidemembers of the frame and preferably arrangedone -nea-r the upper end and one near the lower end of each guide 18.The guides 18 fit over these screw threaded supports and are held in therequired adjusted position by lock nuts 20 at opposite sides of eachguide.

There is thus presented a simple and efficient construction by means ofwhich the yarn receiver is guidedduring its transverse movement so as toprevent any longitudinal movement thereof and by means of which theguides may be readily adjusted to correspond with the desiredconditions.

Having thus described the invention, what is claimed as new and desiredto be secured by Letters Patent, is:

1. A yarn winding machine comprising a frame, a yarn receiver having acore, roll and journals, a winding drum in parallelism with the roll andacting by peripheral engagement with the yarn mass on the roll to effectthe winding operation, means to permit transverse movement of the rollwith respect to the drum as the winding operation proceeds, andguideplates abutting the ends of the roll journals and supported rigidly fromthe frame at right angles to the roll axis whereby longitudinal movementof the yarn receiver is prevented during transverse movement of the rollin the winding operation. v

2. A yarn winding machine comprising the constructiondeiined in claim 1together with means for adjusting the guides bodily longitudinally ofthe yarn receiver axis.

3. A yarn winding machine comprising the construction defined in claim 1in which the guides are supported by threaded supports extending fromthe frame passing through the guides and lock nuts adjustably holdingthe guides in position on the thread ed supports.

4. A balling machine comprising a frame having uprights presentingparallel vertical slots, a beam having journals mounted in said slots, awinding drum journalled inthe frame in parallelism with the beam andacting by peripheral engagement with the yarn mass on the beam to effectthe winding operation, a yarn trumpet, means for giving a traversemotion, between different limits parallel with the axis of the-beam, tothe trumpet during the winding operation, and guide plates supportedrigidly from the frame at right angles tothe axis of the beam andparallel with the slots in the frame, and

means for adjusting the said guide plates In testimony whereof I havesigned my name to this specification.
